LlQUlD-FUEL'BURN ER.

SPECIFICATION forming part Of Letters Patent NO. 734,930, dated July 28,1903.

Application filed August 25, 1902. Serial N0.12O,969. (No model.)

To a. whom it may concern.-

Be it known that 1, JOHN W. NEUMANN, a citizen of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented'new and useful Improvements in Liquid-FuelBurners, of which the following is a specification.

This invention relates to a liquid fuel burner of that kind which is setinto the firebox of a stove or similar heating appliance; and it is inthe nature of an improvement of the device disclosed by Letters PatentNo. 698,408, granted to me April 22, 1902, and to which reference may behad; and one of the primary objects of the invention is to provide asimple and effective construction wherein the draft is not interferedwith to any appreciable extent, so that more perfect combustion will beobtained.

Other objects and advantages of the invention will appear in thefollowing description, while the novelty thereof will be pointed out inthe claim succeeding such description, and said invention is clearlyshown in the accompanying drawings, forming a part of thisspecification, and in which Figure 1 is a perspective view of a portionof a cooking-stove, showing my improved burner incorporated therein,parts being broken away. Fig. 2 is a transverse vertical sectionalelevation of the same.

Like characters refer to like partsthroughout the several figures.

I do not wish to limit the use of the burner in any particular kind ofstove; but for the purpose of showing the function of the same 1 haveshown it in a common form of cooking-stove, the top of which is denotedby 5, the front by 6, the oven by 7, the fire-box by 8, and the flue,which extends from said firebox over said oven to the chimney or likepart, by 9. In the front of the'stove is an aperture or opening 10,controlled bya damper, as will hereinafter appear, for regulating theadmission of atmospheric air to the fire-box. An angularly-disposedplate 11 is mounted in the fire-box, and it has a flange 12 along itsupper edge, fitting against the back of the hood 13.

Below the plate 11 is a troughshaped shield 14, which, it will beapparent, is in the fire-box 8, and the front portion of which extendsthrough the opening or aperture 10. The rear wall and the sides of thisshield 14 extend above the front wall thereof and arehorizontallyflanged, as at 15, the rear portion of the flange overlapping the top ofthe oven at the front of the same, while the lateral or side portionsthereof uphold the hood The innerfaces of the sides of the shield 14 areprovided with ribs 16, against which the ends of the plate 11 arefitted, the latter terminating at its lower edge in an obtuse angularflange 17. The ribs at their lower ends are V-notched to receive theflange.

The several parts before described may be united together in anydesirable way. Some of them, for example, may be made integral. Alongthe front 6 the supply-pipe 17 for the petroleum or other hydrocarbonfluid extends, its inner end terminating substantially centrally of thesaid front and being pro vided with a branch 18, extending into thecombustion-chamber of the stove through the aperture 10. The outlet ofthe branch is situated near the forward end of the lip 19 and is adaptedto deliver the combustible fluid onto said lip, which, it will be seen,is relatively narrow. I

The space between the upper forward edge of the shield 1 f and the upperedge of the aperture 10 is intended for the admission of atmospheric airinto the combustion-chamber,

and the flow of air through this space is controlled by a damper 20,having pintles or journals fitted in suitably-formed bearings in theupper forward side of the shield 14. When the damper is closed, itsupper free edge will bear against the front of the stove, said damperwhen so disposed being at an inclination. The damperhas a pair oflongitudinal slots 20 and an intermediate transverse open-ended slot 21,through which atmospheric air can pass when the damper is shut, tothereby secure the proper degree of combustion. 13y reason of theopen-ended slot, the open end of which is located in the upper edge ofthe damper, the supply-pipe, or rather its branch 18, will not interferewith the closing of the damper, as said branch when the damper is closedis adapted to enter such open-ended slot.

The supply-pipeis adapted to be connected with any source of hydrocarbonliquid fuel,

(not shown,) and the branch thereon, which, it will be seen, extendsinto the stove at an angle, is adapted to deliver the liquid fuel ontothe lip 19. In practice the supply-pipe is equipped with a valve (notshown) for controlling the amount of liquid discharged from the pipe andfor also cutting 0d the same.

By reason of the relatively narrow lip 19, onto which the liquid fuel isinitially dropped and effectually spread, the draft of the stove is notappreciably affected by its presence, as such lip does not interpose amaterial obstruction to the inflowing air. In this way I am enabled tosecure the highest degree of combustion of the fuel. Said lipis unitedto the plate carrying the same in any suitable manner-for example, byrivetingand it will be seen that the sides of said narrow lip are openin order to facilitate the passage of liquid fuel therefrom onto theinclined plate 11.

Oil being caused to flow through the supply-pipe 17 will drop from theinwardly-extending branch thereof onto the lip 19, which is madeconcaved upon its upper side to receive a smallquantity of oil, which isignited. The flame and hot gases will ascend and strike the curved undersurface of the hood 13, which projects the same forward and thendownward along opposite sides of said lip.

Such flames and hot gases then pass below the lower edge of the inclinedplate 11, being directed toward the chimney by the bottom and rearinclined wall of the shield 14, the necessary oxygen to maintaincombustion being furnished through the damper-regulated opening 10.

Having described the invention, what I claim is- In a liquid-fuelburner, the combination of a stove having a fire-box provided with atrough-shaped shield, an inclined plate above said shield, a hoodsituated above the lower edge of said plate, a liquid-fuel-supply pipeextending into said fire-box, and a lip upon the forward side of saidplate located in proximity to the outlet of said supply-pipe and saidlip being narrow with respect to said plate, and its sides being openwhereby liquid flowing onto said lip can flow sidewise from the same andonto said plate.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
